Question:
Since the DTB is compatible with V16, then technically U-Boot can work with it. What
would happen if U-Boot added some nodes to the DTB, but it didn't update size_dt_struct?
Would the value of size_dt_struct still be correct? If not, then does that mean that
U-Boot should reject V17 DTBs?
